Fixed inductors are components used in various types of electronic circuits. They consist of a core, such as a coil, encased in a container, typically of metal housing. Their main purpose is to reduce or block the flow of alternating current, but they can also be used to filter, store or supply energy. They are important components for regulating voltage in a wide range of electronic designs.

The 0819-02J are fixed inductors that provide high inductance, low losses, and an appealing low profile for printed circuit boards. They are available in a variety of inductance values, range from 1.2 micro-henry up to 22.0 micro-henry. They are also available in A, B, C series, featuring wide inductance tolerance of ± 20%, and come in Direct-mount or PC-mount (SIP) packages.

The 0819-02J are high-performance, high-current, shielded inductors designed specifically for wideband applications that require EMI suppression. It can be used in DC-to-DC converter switching regulators, SMPS, PLLs, antenna systems, etc. Its micro-sized dip construction allows for tight, space-saving integration.

The working principle of the 0819-02J is based on Faraday’s Law of induction. This law states that an electric current in a circuit induces a magnetic field in the surrounding area, and, conversely, a magnetic field that changes induces an electric current in a circuit. That is essentially how an inductor works: when an AC current is applied, it causes a changing magnetic field, and this in turn produces an electric current.

The inductance of the 0819-02J is determined by core material and core size, the number of turns in the coil, and the core material’s permeability. The 0819-02J has a Permeability (magnetizing force), which is considered a semi-magnetic material due to its large size and results in higher inductance values. The tighter the coil, the higher the Inductance value.

The Permeability of the 0819-02J is important because it affects the efficiency of the component. Poor efficiency in an inductor results in high losses in energy, and can be the cause of performance degradation or even component failure. The 0819-02J achieves a high Permeability by using high purity materials in its construction.

In addition, the 0819-02J has a high current rating to handle power dissipation requirements in high power applications. The package provides an electrostatic shield to protect against noise interference. It also features an optimized lead length to minimize stray inductance, leading to improved noise immunity.

Overall, the 0819-02J is a high-performance fixed inductor, suitable for a wide range of applications. It has high inductance values and an impressive current rating. It offers a high degree of noise immunity due to its shielded construction and optimized lead length. Its micro-sized dip package provides a low profile and excellent integration into printed circuit boards.
